Mike, this valve is also called a 'Combination Valve' because it not only proportions front and rear pressure but also adds safety to the brake system. It does two jobs.

No such pin as you mention. 2 inputs, 3 outputs, 1 idiot wire plug-in (currently not utilized). I took the 1st MC back, and got another just like it. It seems to be working better. I finally got the fronts to bleed!!! And the front wheels are done. This has not been fun. Now the rears won't bleed at all, haven't moved an ounce from the resevoir. I can see bubbles move forward/back as the pedal is pumped (1 man bleed kit), so I know that the lines are clear and not kinked. At least some air is getting moved at the rear wheel cylinder as the pedal is pumped. I did bench bleed the MC, that went fine. I'm going to let it sitt over night hoping to let the gravity do it's thing. I don't think I've ever had this much trouble bleeding brakes!! Thanks for the suggestions.

And where can you not get fluid? Front/rear/both? For 72 anyway, there is a pin on the proportioning valve that must be pressed in to get flow to the rear.
